I'm currently working on a web app [0] to track my running data, but it has a long way to go and is frankly fairly useless at the moment.

It's sometimes much more challenging to dive into an existing project, learn their frameworks/style/design, and work with existing contributors.
However it's also much closer to what happens on a real development team. Whereas a project with a single author can show coding skill, working in a large open source project shows collaboration, communication, and soft skills as well.
It is a huge gold star on a resume in my opinion.
"Check out this thing I made - runwithjohnjs.com" will have a much greater effect.
For bonus points, write about how you built it (just use dev.to).
A cool project will get you in the door, then you just have to perform well on the interview (for which many prep materials exist online).
Our dev environment set up, coding standards, testing standards, release process etc will all be taught when joining the team.
I haven't seen it before but if you were able to say I fixed these bugs on this project (that had the same stack as my teams') then it would be something that stands out - I should take my own advice!
