You'll probably struggle to print things on an FDM printer as transparent as you can with resin printer though.
Heated bed is a must to print anything useful ABS, PETG etc... As for auto bed levelling I have it on 4 of my printers, but the one that give me the least hassle is my Ender 3 with manual leveling.
It's great fun, I get the impression that you're the kind of person who'll make it do want you want it to do through clever design.
