In D20, every fight is cinematic. If you give them the same feel in your game and have an end goal separate from killing monsters, a huge 3d environment and a ticking clock of tension then you’re emulating it perfectly.

This campaign, I've been using notion but the previous campaign I used a google sites to make nesting webpages and keep campaign info on there. I made all the pcs authors so they could also update their characters, add information, etc and it worked out okay for a front facing solution. We never hit publish on the site so we didn't share it beyond our group, of course. As long as you have a way to keep yourself organized it's much easier to deal with the twists and turns that campaigns take.
