Messed up a little today with my boss - thoughts on how to fix?

I'm a senior engineer with 8 YOE. Working at a regional non tech company as a product engineer. I am considered a good performer relative to the others at the company and am generally well liked.

For a variety of reasons I've been really frustrated with my career growth over the last year. These reasons are totally valid IMO and I've hinted to my manager that I would like things to be different, but nothing has really changed (partially on him and partially on the company). I really care about the company and the product so I want to make things work here - especially when I know I can have a lot more impact than I'm currently having.

Today a project I really wanted to lead got deprioritized for what I consider to be a silly reason, without any input or discussion with me. I was extremely frustrated and ended up DMing my manager asking to speak, saying that I've not been happy with the career growth and how I've been assigned work over the last year and that I want to understand how the company can support me and my career growth more in '25. He said that he is down to chat on Friday as the earlier part of the week is busy for him, then asked me how my weekend was and made a joke based on my reply.

In hindsight I now realize this was a silly thing to do. The message, while not rude, was maybe a little too firmly worded and was definitely emotionally charged. I have a great relationship with my boss - he got me a good pay bump last quarter, is supportive of me taking time off, and is a genuine guy - so I am worried about having rocked the boat. I also think I can't walk back the message because it was too strongly worded.

How can I make the best out of this situation?

I'm thinking - tomorrow I DM him, saying that I'm sorry if the message came across as aggressively worded and that I've been frustrated with the project, and that it comes from a place of wanting to do well both on a personal level and for the company (both true). Then on Friday I meet with him and clear the air, framing it along those lines. Thoughts on this?
