I’ve been told (haven’t done it myself) that the ps5 controller pairs extremely well with the steam deck + dock. I would ask around though- I have an actual Steam Controller that I use, myself, but I don’t think you can buy those anymore.
Usb-c port, so yes, though you may need an adapter… And a long cord.
Unless you also grab the dock, but then you also need a controller.
Not to mention you can just toss a 1tb SD card in, with no skills needed and only minimal cost difference.
Yes, accessing your data off an SD card is marginally slower than off an NVME ssd… but we’re talking, iirc, milliseconds. If it really bugs you later down the line, then you can upgrade the SSD.
If you’re willing to deal with terminal, you don’t need a gpu at all. You can merely connect over serial (which could be a DB8 connector, or an ethernet connector, or whatever), and a directly plugged in screen/keyboard (which is usually also supported, though maybe not over HDMI or anything) will also work.
And to be honest, if you want to play with servers, you should get used to terminal- it will do you a lot of good in general.
Because none of those emulate current generation systems.
People act weirdly entitled about Nintendo product, throw shitfits when Nintendo reacts exactly like Sony or Microsoft would to them doing the same thing, then act extra hurt that Nintendo did it.
