Depends on the production. Lots of actors in the olden days loved getting a series because it meant they were closer to home and had a consistent schedule. Very little location shooting out of state, giving them more time to spend with family. Summers off meant the ability to do movies or stage work if they wanted to.

Lucille Ball’s daughter has said in interviews that Desilu ran a tight schedule and everyone went home at a decent hour because Lucy wanted everyone to go home at a decent hour (including her).

Unions need to flex their muscle if cast or crew is having to work excessive overtime.

Network TV is still at 20 episodes per year.

Anthologies have been very popular. Change up the cast every year. That keeps costs down even more.

Divide the crew into groups. Have an episode focused around the command staff, an episode focused around engineering, an episode focused around sickbay, etc. Have the casts be mostly separate from each other barring the occasional cameo appearance or viewscreen conversation. Basically treat it as several shows that happen to take place on the same ship.

Yeah with less references and Legacy characters popping up when lower decks just does lower decks and doesnt do jokes its really good normal start trek. Also as a joke series i only wish no other series would reference it as it hurts the jokes and hurts other series trying to keep canon with it. But i also hate the concept of canon. Keep what works as a jumping off point for what comes after but also prioritize the story you are telling over everything else.
