As to 5-3-3-2 with the 5 card suit in a major, practice amongst Acol players splits three ways. Some always open 1NT, some only when the suit is poor, some always open the suit. I'm in the middle group

There are other groups too: open 1NT with 5♥ but 1♠ with 5♠; open 1M with (35)(32) but 1NT with (25)33; open 1NT with (25)33 and 1M with any other 5M holding; or open 1♠ with 53(32) and 1NT with any other balanced 5M holding. There are probably also a few others around, particularly when you get into variations of suit quality rather than just distribution.

I play 12-14 with 1 partner of modest bridge ability. (he is uncomfortable with strong)

He insists on rebidding 2NT over a 1NT response with 15/17 and 3NT with 18/19 when a minor OR Major is opened, I do not like this and would hearitly support the other posters who suggest rebidding the better minor over a forcing NT.

Yeah, if you want to play forcing 1NT responses you need to be comfortable with treating 5332 in first instance as a 2-suiter. For that reason you can't play forcing 1NT in response to a minor suit. I suppose you could play a short club system where 1♦-1NT is forcing but what's the point? The 1NT response is quite descriptive (with the negative inference from not making a 3♣ WJS or IJS), so opener is in a good position to pass 1NT.

It is a disadvantage of WNT5cM that with 5M332 and 15-16 points, when it starts
1M-1NT
2m-2M
you pass with 15 and bid 2NT with 16. You'd rather have opened 1NT in the first place. But those who play French Standard or similar (where 1NT is 15-17 but denies a 5-card major) have the same problem.

Good point Glithin, thanks. I forgot to mention the Hearts / Spades aspect.
