Three questions about Drupal:

1. What mechanisms exist to put a site into maintenance mode?
   I know the UI and drush — is there a complete list?

2. Where can I check who enabled it? 

3. Is it expected that, after leaving maintenance mode, a site
   sees a burst of requests and a jump in database server memory?

Thanks.

There is a third way maintenance mode can be enabled. During a deployment, if something goes wrong during config import or some other step, Drupal will automatically put the system in Maintenance Mode. 

I don't think there is a way to audit who did it. It would need a custom solution for that.

Contact me to contract me for D7 -> D10/11 migrations.
Or anything really. I'm friendly, and open to work or conversation.

Yes, that is true. Drush's updatedb automatically enables maintenance mode:

updatedb
Apply any pending database updates. Automatically enables maintenance mode during the update.

From https://www.drush.org/latest/commands/updatedb/

I am not sure if config:import does as well, but maybe?

I think I was probably incorrect about it being on config import. And it makes sense that it would happen during the DB update rather than the composer update. I am thinking that drush updb enables maintenance mode while it starts, and then disables it when complete, meaning that if an error happens in the middle, maintenance mode is left enabled.
