Your job title encompasses the highest-order bits about who you are, professionally. The value is much more between organizations than within a single one.

If you plan to stay at one place for a long time, it's much less important. You have a chance to figure out how things 'really' work in practice. I know a guy who is a senior architect, and everyone refers to him as that at his company, but his actual on-paper title is something like "project technical lead". It's just not very important if you are going to stay there for 20 or 30 years and chase deep breathing metis.

I don't have the same career outlook, so my job title is important to me. I actively negotiate for it. My own title is "senior DevSecOps engineer". Criticism of the acronym notwithstanding, this paints an instantly legible set of competencies around what I do best, what I do adequately, and what you probably would get better value for money paying someone else for. I'm probably pretty good at vulnerability management and securing CI/CD pipelines. Optimizing weights on our anti-spam logistic classifier is probably not the kind of thing I can do well. Etc., etc.

Titles mean even less across organizations. Any interviewer worth their salt is going to hire you and level you based on how they ascertain the level of scope , impact and dealing with ambiguity you dealt with.

You can be a “CTO” of your little 5 person company - you might be leveled as an mid level software engineer at BigTech

metis?
