In FRUA it's up to the design author whether you can rest everywhere or only in specific places and whether there are random encounters or not, and at what frequency. My guess is that it might not have been possible to re-create the random encounters of the original gold box games 1:1 or that it would have used up too much space, and that the author thought it would be the lesser evil to do it like this (unfortunately the number of dungeons/areas is limited in FRUA, and there is also a limit in events and texts per dungeon/area).

There are definitely designs that allow you to rest anywhere, I think lots of them do, actually, but off the top of my head, I can't tell you which design uses which system. I suspect that you will find resting restrictions more often in the classic conversions of AD&D modules than elsewhere (in many it's also considered part of the challenge - often the dungeons have safe resting rooms somewhere, and the challenge is to survive and use your spells sparingly until you find shelter). I think the FRUA community as a whole is not that fond of random encounters in FRUA, as they can become very tedious if overdone by less thoughtful authors, but quite a few of the gold box style fans still use them occasionally.
I'd understand if you don't care enough to create another account elsewhere, but if you'd really like to know more details and give it another try, I'm sure the folks at the FRUA community forum would be glad to help you and provide more helpful answers than I can at the moment. The author of many classic conversions and probably also the ones you have issues with, Ray Dyer, still visits those forums himself occasionally, so you might be able to talk to him directly. (He is a very nice and helpful guy.)
Btw, if you have some rudimentary knowledge of the FRUA editor's basics, you could also "cheat" by manually toggling off the resting restrictions in the designs you play, although you'd have to do it in each dungeon/area separately.
