Just a thought -- one of the benefits of using the actual call sign (RS0ISS, PSAT, PSAT2) rather than ARISS or APRSAT is for the record.
For example, I am calculating the Az/El of each contact based on the digipeated (PSAT*) path. When the digipeated path is ARISS or APRSAT there is no good way to clarify which satellite participated in the packet.

See the Az/El columns for PSAT; I plan to add Az/El for others sometime soon.
As a consumer of the data, I prefer seeing the individual call sign. As the user of the radio, I can see how using APRSAT for everything is more convenient.

Yes, that's correct. FalconSat-3 doesn't digipeat using the generic ARISS or APRSAT paths.
Agreed, it's a pain to have to keep changing PATH, baud rate, and data band between FalconSat-3 and the other packet satellites. At least there are only two configurations to have to toggle between. Once you've done it a couple dozen times, it becomes second nature.
Yes, PSAT2 (and apparently also AISAT) may need to use Narrow FM mode, but the mode can be easily programmed into memory channels. I just set up a different set of memory channels for PSAT2 and AISAT to set that mode and enable (crude) Doppler correction. I haven't used them yet so don't know if 5 kHz steps will cut it.

Regardless of the other operational requirements of FalconSAT-3, you are saying FalconSAT-3 will not digipeat using the generic paths. That means the text in the links provided is incorrect. Or is there some other qualifier I have missed?
PSAT2 is also a different beast apparently. The text in the link imply APRS uplinks are narrowband. From the PSAT2 link:
Uplinks: 145.825 MHz narroband [sic] FM packet and 29.4815 MHz SSB PSK31 User Station Software Configuration: First bullet - Radios must be in Narrowband and track to 1 KHz Doppler on the uplink.
The reason for asking is to be able to make as few changes to an HT (D72) as possible. And the main use is to achieve a digipeat. When a satellite is the only APRS network available it could be a useful way to get information out.

FalconSat-3 is a different beast: 9600 bps vs. 1200 bps, and crossband at different frequencies than the 1200 bps packet satellites. If you want to be digipeated by FalconSat-3, you need to use the PFS3-1 PATH.
