Is there any particular expression, proverb, colloquial slang or the like to state a case when someone likes neither one thing nor its opposite?
Example 1: "I don't like cold weather because it's cold, but I don't like warm weather either because it's too warm."
Example 2: "I don't like when you don't let me decide what to do. If you do let me decide what to do, I don't like it either because I don't want to decide what to do."
These might have the flavor you're looking for.
From https://www.wiktionary.org/:

Catch-22: (idiomatic) a difficult situation from which there is no escape because it involves mutually conflicting or dependent conditions.
no-win situation: any situation that is certain to end in failure or in which any favourable outcome is impossible.
Be in two minds (about something) — Macmillan

Undecided — Dictionary
adjective 1. not decided or determined.
2. not having one's mind firmly made up.noun 3. a person who is undecided

I didn't find negativist, naysayer, or contrarian to be quite right.
How about unpleasable?

The situation ('case'?) is actually described in the Bible ('the like'?):
We played the flute for you, but you didn't dance; we sang a lament, but you didn't mourn!
[Matthew 11:7; Holman Christian Standard Bible]
I've seen a commentary describing some people who criticised a pastor who 'spent too much on a car', and then complained he was giving a shabby appearance when he swapped it for one a few hundred dollarmarks less.
