Would it be accurate to say that this (Amazonia-1) is the most sophisticated satellite developed in Brazil? ISRO/India can derive gratification in that they are a part of it! Together with the launch carrying the first ever Indian private sector satellite,
it makes the PSLV C-51 quite tantalising.

Yes, this is.

More from our official team:
"Amazonia-1 will be launched by ISRO's PSLV-C51 mission, on February 28, at 10:24 am, local time in India - at 1:54 am, in Brazil. A few minutes later, the satellite will be crossing the Equator heading south. Its orbital dynamics have been calculated in such a way that, until the end of its 4-year useful life, Amazonia-1 will always cross the Equator between 10:15 and 10:45 local time, wherever it is passing.This guarantees the same lighting conditions on the earth's surface, allowing for a better comparison between images acquired from the same locations throughout the year - something desirable for several remote sensing applications."

21 satellites on this launch, and the time has shifted to the left by 1 minute:

PSLV-C51, which is the 53rd mission of PSLV, will launch Amazonia-1 of Brazil as primary satellite and 20 Co-passenger satellites from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 1023 Hrs IST on February 28, 2021 subject to weather conditions.

PSLV-C51/Amazonia-1 is the first dedicated commercial mission of NewSpace India Limited (NSIL), a Government of India company under Department of Space. NSIL is undertaking this mission under a commercial arrangement with Spaceflight Inc. USA.
...
The 20 co-passenger satellites include one from ISRO (INS-2TD), four from IN-SPACe (three UNITYsats from consortium of three Indian academic institutes and One Satish Dhawan Sat from Space Kidz India) and 15 from NSIL.

Interesting - the illustration of the PSLV C51 launch vehicle on this page shows a PSLV-QL version, not the DL verision.

The ISRO article refers to this mission being undertaken with some kind of agreement with Spaceflight Inc of the US. What is the US role in this mission, tracking, technical support?

It is most likely primary and secondary payload management and/or their facilities for SA (Spacecraft Acquisition) and LEOPS (Launch and Early Operations).

Amazônia-1 launch campaign (in Portuguese) from INPE http://www.inpe.br/noticias/noticia.php?Cod_Noticia=5680

Google translation...

In the first week of February 2021, INPE's technical team concluded the exclusive activities of the Amazonia 1 satellite at the SHAR launch base, in Sriharikota, India. The phase of exclusive activities and integration with the separation system was carried out in the laboratory called SP 1 B (Satellite Preparation 1 B). From this stage, activities must be carried out in the laboratory called, SP 2 B (Satellite Preparation 2 B) and finally, in the launch tower (SP 3). In the laboratory SP 2 B, the activities of checking for tightness, filling of the fuel tank and integration with the fourth stage of the PSLV will be carried out. On February 5, 2021, Amazonia 1 was transported from SP 1B to SP 2 B. Although the distance between the two buildings is approximately 7 km, the transport took about 90 minutes. This was necessary to meet the transport requirements of Amazonia 1 and also the security protocols of the SHAR base. Amazonia 1 has already been connected to SP 2 B and has been verified to be in perfect condition to proceed with the schedule of activities. Thus, to date, all planned activities are being carried out according to the schedule and successfully concluded and Amazonia 1 is on its way towards launching on February 28, 2021.

They appear to have dropped two satellites from the mission. Now, it's 19 satellites in total, not 21 as stated earlier.

Does anyone have any information about SAI NanoConnect-2 ? Btw, It is not part of spaceflight's list.

I have the same data, this cubesat comes out as sent by the United States and a photo of a conventional cubesat, but the specifications are not known.
Does anyone know anything else about this cubesat?

As Conexion Espacial has also figured out:

SAI-1 NanoConnect-2 is a 2U cubesat from UNAM (Mexico City) in collaboration with Space AI (Mexico City and San Francisco).
The Space AI (SAI) bit is a software-defined-radio processor chip. The satellite was built in Mexico. It will be deployed
by a Maverick Inc. Mercury-3 cubesat dispenser, and (the US-based) Maverick is handling the launch booking with ISRO, which
is why the ISRO press kit thinks of it as a US customer. Mass is 2.275 kg.

Have they retired the CA variant with no strap-on boosters?

They seemed to be using two or four boosters more frequently even though those missions are within the CA payload capacity.

No. It is still available as a launch option and are flying the three other variants to allow more rideshares as their is high global demand.
