If you have literally no experience at all, I’d pick and choose some great standalone episodes to get started with.
Some ideas:
TOS: Balance of terror/Space seed.
TNG: Drumhead/Darmok.
DS9: The House of Quark/Trials and tribulations (harder to find good standalone episodes as so many of the best are part of the main plot.
VOY: Eye of the Needle/The Void.
The 2 parter DS9 and voyager opening episodes are both also pretty good places to start.
