I run Concourse CI for my personal stuff with the code in Fossil. It works decently enough, I like that it's somewhat extensible, but I have hit use cases that it can't really do like building an Alpine Linux cloud image.

As for YAML vs TOML, I am mostly sick of YAML, and I really like using TOML to configure Caddy, so I thought it might be good enough for CI config. I feel like it would be worth exploring, but maybe something slightly more complex or custom would be required.
