It's not the format that's the issue, it's the execution. There have been good and bad seasons of Trek and other franchises that were serialized or semi-serialized, and good and bad ones that were episodic. People have their preferences, but there's nothing inherently better about one format over the other, though I will say episodic does allow for a greater amount of flexibility for the production staff, while serialized generally works better when you're running a tight ship and the number of cooks in the kitchen is kept to a relative minimum.
One thing I have noticed about some of the more poorly executed serialized seasons, is that they try and stretch four or five episodes worth of material into ten episodes or however long the season lasts, which results in a lot of filler episodes where nothing much happens, false or misleading out-of-character behavior / plot developments or cliffhanger endings that go nowhere and have no consequences thrown in to keep the middle episodes more exciting, and an ending that is anticlimactic after so much waiting and buildup.
I think Enterprise S4 handled that right by being a hybrid of short serialized storylines that lasted two or three episodes, and occasional standalone episodes in between. If you lost interest in any particular storyline you only had to wait an episode or two to be in a new one, and there wasn't any of the excessive padding of storylines to fill the whole season.
Likewise, Deep Space Nine had loose sometimes overlapping seasonal arcs like the Bajoran Circle, The Maquis, encountering the Dominion, the Klingon War, and then the Dominion War, but it was always interspersed with standalone episodes to give people a break.
So, I'd say the best solution for a show that's having trouble making a serialized season of consistent quality (PIC and DSC) would be to hybridize it into a combination of 2, 3, 4 episode mini-arcs interspersed with some standalone episodes. There's no rule that says your serialized story has to last the entire season.
Or just go full episodic like SNW, which has been fantastic.
