There is the Sovol SV07 for about 300€-ish. It comes with Klipper and should check all your boxes. I bought the SV06 Plus two months ago it works OK. You have to tighten all the screws and actually read the manual, but that’s it. If you want a guaranteed problem free OOTB experience, you have to buy Prusa (top quality control and software) or Bambulab (not really hackable but runs well) for 600-800€.
You are correct, PLA is per definition food safe. The problems you mention are also correct. There are two other major problems: There can be residues from other prints in your printer which contaminates your prints. The manufacturer does not label their filament as food safe. There are no list of additives which could be harmful.
There are ways around some of the problems like smoothing with heat or chemicals. Most of the time it is no major concern. Containers for cutlery? No problem as long you are not selling them. Container for food itself like lunch boxes? This is something I personally would not risk. Lids for containers with no direct contact to the food? I think you should be alright. Just don‘t do it commercially.
