Do you need to see the first two Spider-Man movies before this?

Yep. Everything you need to know is quickly recapped in the first 30 seconds. A general knowledge of the MCU is certainly helpful however.

i would say it's much more useful to have seen the first two raimi films than the previous holland films. if you've seen them, then you're probably fine.

Yes, you need to see the first seven Spider-man movies before this.

Civil War too, and Infinity War and Endgame.

With the current MCU, it's all linear so you need to watch the previous to understand the current else references and such will get confusing.
