I know what you mean dude.
My first recommendation is my personal favourite deck,
Queen Marchesa. This deck used to be my Mono Black Yahenni Aristocrats deck, but that deck was really oppressive with hand attack and
grave pact soft locks stopping people gaining any kind of presence in the game. Switched it up to
Queen Marchesa and haven't looked back. Mardu is great for Aristocrats, but most importantly, it's all about the Monarch. The Monarch is an excellent, incredibly fun multiplayer mechanic and, even though that deck is still pretty strong in my meta, people don't groan when I pull it out. Everyone has fun because the Monarch is that good, and naturally my deck is built to take the most advantage of the monarchy and maintain it as much as possible.
The Command Zone did an episode on this subject a few months ago. I can't remember exactly what all of their suggestions were, but I remember their list seeming pretty good. Episode can be found here:

I don't think the Commander is as important as the overall strategy. Naturally, there are times when you just want to play that degenerate stuff, but if the focus is on table fun, then just focusing on a "fair" build is a good place to start.
Other than that, I think the main thing is just for a deck to be meta appropriate. I love combo decks, but if I build a deck that is able to combo too quickly or consistently, I take it apart because that's not good for my casual meta. I still play combo decks, just ones that are more obscure and less consistent. My buddies don't mind losing to combo if it was later in the game and I had to
jump through hoops to do it and they had chances to
disrupt it.
That is obviously a lot harder to do if you don't have a consistent play group though.
I guess another way to approach it is to think about decks you've enjoyed playing against. What games have you lost and thought "damn, that deck was cool"?
