After researching triggers, I've only come up with thing showing how to update, insert and delete. It seems like that's even part of the syntax itself. DB2 Docs on Triggers
Is there any kind of trigger, or something similar, which would let me track a larger set of actions, things like SELECT and ALTER TABLE?
We (unfortunately) share a database with some teams which we don't strictly trust to not do things like run insane SELECT statements (locking up the databases) or ALTER TABLE without us knowing. We'd like to be able to track when these happen and what user made the change.
Please, no suggestions recommending we get our database separated in some way. We're working towards that in the long term, but we need this in the short term.

The link for DB2 docs given in your post points to IBM i. Is your database DB2 for i?
For IBM i, you can use detailed database monitor to capture all SQL statements including DDL commands like alter table. However, running detailed database monitor for all users causes performance problems. We were in same situation as you with multiple teams using same server as database. We ended up writing custom user exits to capture all SQLs (with user details) in our case.
