A couple of notes from my own history...

When you are expert on a topic, try to convey your comfort with the topic by entertaining questions from others. This is the most honest form of bragging. Some people say "learn how to sell yourself" but I think this is more nuanced.

Start learning SQL. Don't be afraid. Don't wait. It's a seed worth planting early.

Be kind, but also be firm. When someone is in a role that demands way more than their skill/experience, it is crippling. You have to speak up. It is worth learning how to be kind as well as diplomatic when you make your case.

The developers that are hard to replace are the ones who leave a build systems anyone can use/maintain. Cryptic codebases rarely hide a bunch of value; more like a bunch of bugs.
