I've bought pretty much all of the pis over the years, and was shocked at how capable the pi5 is at doing everything I need from a computer, including programming in a heavy IDE. Unfortunately, it's a non starter for doing anything serious on though as there's still AFAIK no support for full disk encryption in the installer, even if installing to SSD. Such a lost opportunity to be a 'PC' replacement.
Can't you just run a normal Linux distribution if you want that, or does that not work any more?
