Would you recommend to use a RPi 5 or a second hand Lenovo mini pc (i3 6100t, 8gb ram) or something else?
Raspberry pi: No. Or, at least, not without doing something to make sure you have a real storage backend and aren’t just running it off an SD card. The wear on SD cards is exaggerated and largely minimized if you use an OS that is configured to be aware of it but you are also increasingly relying on a ticking time bomb.
Mini PC/NUC? I am a huge fan of these and think they are what most people actually need for stuff like home assistant, adguard, etc. Just understand you are going to be storage limited sooner than you expect and you can oversubscribe that CPU and memory a lot faster than you would expect.
My general suggestion? Install proxmox on the mini PC and deploy on top of that. If/when you decide you want something more, migration is usually pretty easy.

I use a retired business laptop. 16GB RAM and Linux, mapped some shares from my NAS. Low power high performance.
