4a is end of life already, so no firmware updates from Google. GrapheneOS has legacy builds available for it but doesn't recommend using them, and they might go away anytime soon
get a used device which is still properly supported, don't buy brand new e-waste
not OP, but I have to run fronted and backend of a project in docker simultaneously (multiple postgres and redis dbs, queues, search index, etc., plus two webservers), plus a few browser tabs and two VSCode instances open, regularly pushes my machine over 15gb ram usage
I've had to swap Firefox on my laptop for the deb package, the snap took like 5sec to open, whereas the deb opens instantly. Other than that, i don't see much of a difference, but i run into sandboxing issues quite often (same with flatpak though)
I just switched to a degoogled phone and Aurora recently, and it worked fine installing 30+ apps. When you get an error, try logging out of Aurora and start a new session, maybe the current Aurora proxy your phone is using is down
