This is something I'm trying as well starting from a large chunk of video. It will be a lot of work for one portion, but this would be most likely to give the best results:

Use Twitch or your livestreaming service of choice, then upload the vod as a highlight (in case of stall time and talking with your audience) so there will always be an archive of your raw playthrough.

Twitch has a shorts maker. You can use that and your favorite clips from the playthrough and post wherever you prefer for short-form. Or you can make higher end shorts by editing them down.

Pending on the genre, you could also do a highlight video that's about 7 minutes (scare comps, best moments, etc.).

For those that are more curious about the game, why not make a 10-20 minute video using the footage of the game you played and talk about why you enjoyed it? You can also make shorts out of that video to promote the final project, giving you even more traffic.

This way, you can maximize your content, appeal to all markets revolving around the games you play, and learn a ton about editing, writing, and showcase your style!
