Go back and finish Deep Space Nine if you didn’t watch it consistently, it’s great and probably the most adult Trek. If you’re looking for less of a commitment, Strange New Worlds is great. The only plot point you need to know going into it is
spoilerPike has seen his future and knows he’s destined to become severely paralysed
Discovery is pretty standalone but it’s a very odd show. Everyone is very emotional and every episode is super dramatic. Not to everyone’s taste but good if you want a Trek that reflects more modern TV.
Enterprise gets quite good as well, despite it’s flaws.
