I love the way you introduced that:

Does this sound familiar to you?
Are you a woman?

That was a lightbulb moment for sure. I recognize a lot of what you describe. I'm a woman, and also a serial procrastinator and I'm sure it's partly caused by some subconscious feeling that things must be perfect.

For me, it helped a lot when I heard about the concept of "satisficing", and recognized that there's something to be said for submitting a piece of work that's acceptable, rather than spending loads of time trying to making it perfect. I also found this video super helpful (it's titled the habits of effective artists, but really it's helpful for any creative person). In his second point, he talks about how you learn the most in the early stages of a creative project, and then the last stages - the perfecting phase, if you want to call it that - is usually not that helpful for learning anything, it's just time consuming, so an effective artist should aim for volume, not perfection. Easier said than done huh :D
Thanks for bringing these things to our attention. Noticing and thinking about these problems is definitely the first step towards doing something about them.
