Edit: It works! Not beautiful and shows a concerning amount of "Error" lines on startup but it will do. I got VSCodium and ESP-IDF running, at least – and CMake isn't awfully slow despite it being a crappy 4GB RAM machine (not easily upgradeable). The first boot took a while and I haven't rebooted since, I guess it will be below 30 seconds next time (Mint on same machine but HDD was about 1 minute).
Edit: I hope I chose the right kernel here, surprisingly not much info online on this! Also, I picked "targeted" because the 10-year-old system does not use any cutting-edge hardware and all drivers should be auto-detected, I think.
After some experience with Linux Mint, I gathered the courage to try another distro. I'd like to turn an old laptop into an IPTV receiver plus FTP/OpenVPN/HomeAssistant server with occasional desktop use. I first installed Windows 11 just in case my family needs to use it (it fucking sucks, the built-in PS/2 keyboard doesn't work half the time but that's an issue for later) but now I'll be turning it into a dual-boot setup with Debian as the primary option. Please give me some encouragement, I'm really afraid of new things.

KDE Plasma is very nice if you come from Windows and don't mind an environment that's somewhat heavy on performance - personally, I think it's the closest, modern Windows-like experience. XFCE is very lightweight, but not very modern, as far as I remember.
Don't forget, you can also install multiple environments and then pick one from your login screen; that way you can try them all and see what fits best
