3NT is a very bad bid. 1NT was already a bad bid. I should know 'cause I use to make them a lot.
As long as you continue to play against this kind of opponents and getting these results you will continue to make the same mistakes.
Why is 3NT so bad when I have a good idea LHO will lead a spade? Against stronger opponents I would probably just try 4
♦, but I would certainly be less sure what would be best.
Also, what would you have opened instead? Do you think the hand is worth showing 15+ if partner responds 2
♣? I won't have a problem after any other response if I open 1
♦, but I don't see any problems after opening 1NT either.

I play that the other way around. 3♣ would be "liking those ♦" whereas 3♦ would be "I'll begrudgingly play your ♦". What should one assume with a pick-up?
Probably your way, but it might be location dependant. My way is common in my local club.
There are some small theoretical advantages* to my way, but being on the same wavelength is much more important.
*For example, with a weak hand with both minors, responder can transfer to diamonds planning to pass opener's reply. It also hides responder's hand when opener doesn't like diamonds, so the opponents don't know whether responder was looking for 3NT, or just signing off.
