I have around 50 flavors right now and it is still growing, right now I have 3 containers for holding the flavors, 1 for fruits, 1 for sweeteners and one for custards etc, but trying to find the flavor I want is a PITA,
I started out the same way as what you have, plus tobacco, bakery and odd and ends added it your list.
I thought I was really organized ... out smarted myself as it grew
When I topped 200 flavors, I dumped them all out and re-named the containers with the company name.
It's basically still a PITA, but it works better.
I do still separate out the nuts, and boozey flavors, because there aren't as many of them.
A lot of times I use a recipe that uses all FA or VZ or TFA or etc etc, and then it becomes easy, as I only have to dig through one container.
It's just something I'll have to put up with until I find which ones are the "best of the best", and I can dump all the yuk's
I don't need 4 or 5 of the same flavor, ..just the best one ..(to me)
