After the new Spiderman, I started binging all the Netflix stuff since I had skipped them since they weren't a part of the MCU. I'm up to Iron Fist Season 2. If they wanted to, they could fit them into the MCU as far as I can see. They reference the events of the original Avengers movie and that is about it. I believe Captain America is the only name drop. They mention Hulk and Thor without using the names. There is Hammer tech with the Hammer logo, but haven't mentioned Justin Hammer directly. Not sure if the timeline hits the snap or not so that might require an explanation. I would think they would use the same characters with the same actors and do their own thing. A continuation of any of the series would be interesting, but I doubt that would happen. It would be too much of a different feel I think. With the exception of Defenders, all the Netflix shows are 13 episode seasons with nearly one hour run times per episode. That it is twice the episodes and probably about 15 minutes or so more per episode than any of the Disney+ series.
