theres a reason all roads lead back to the ender 3 pro! its a wonderful starting point at that sub 300 dollar price point, you can even go for the v2 which is a similar machine with the glass bed and silent motherboard stock! as far as accessories go the great thing about 3d printers is they dont require much out the gate but id definitely look into getting a raspberry pi to get octoprint (a really nice wireless solution for your printers!) but past that a spool or two of PLA is enough to get you going!
