So I do like Star Trek a lot, especially TNG, DS9, and Below Decks. Voyager and TOS are fine. Space socialism is pretty good and I can't get enough of it. There are a few common tropes that irk me. tho.
-
Baseball is cracker Amerikkkan nonsense - You telling me that all these different species and planets get together to chill, and the vibe they're gonna channel is Ohio?? Football (soccer) or some version of hockey make a lot more sense, you can pick up and start playing immediately. I can't imagine Worf wanting to learn all those pointless rules about balls and strikezones and fowls. Sisko is arguably the best captain of any series, and I really get pulled out of an episode every time he drops some awful baseball trivia. It's only slightly better than Nascar. I actually know one Scottish person who really likes baseball, and he's literally the worst person I know.

The tribunal - It's so damn common. It seems like every season there's got to be a court-martial, hearing, or appeal against a Starfleet decision. I guess Law and Order is big there. It's probably a minor critique, but it does reinforce the ideology that Western courtrooms are fair.
-
Kirk is a sex pest - This has been said to death, but leave your subordinates alone.
-
Poker in TNG - Poker has to be the worst form of entertainment, and I genuinely like maths. I blame TNG for reigniting the poker craze of the 90s and ruining all my guy friends' personalities.
Baseball is a dead sport the final world series in star trek was 2042, only a few weirdos know what it is let alone play it. Sisco being a fan of baseball is similar to Archer being hyped on water polo in enterprise. It's a super niche interest and the only known league in the universe is on Cestus 3 and only has six teams. I'm not sure at all why you brought up Scottish people in this. There is instance of a Scot playing baseball in the franchise. Here's another thing, baseball is the best sport cinematically. Patrick H Willems made a long video essay about it but the setup of the field and the tension and release angle works better for TV or movies than a sport where people are running around all the time.
My biggest pet peeve is Voyager.
