I think Glass Onion is a fairly easy view, so you'll probably settle in with it.

We are still working our way through Sandman, having taken a long break in the middle due partly to getting other things watched before subscriptions ended. There was a lot of enthusiasm for it but I've been finding it a mixed bag.

I think Rebels doesn't cross over with Rogue One until after the series ends, so it's more like there are some subtle shoutouts in the film. Glad you've been enjoying it and will come back to it again. There are some wonderful storylines ahead.
