I think on the mysql front there are a few alternatives (I use postgres now - and if there was any way of going that route, I'd do that instead). I believe the pure python version is the popular choice these days [0].
I mentioned it because when I went through the process, I was looking for py3 support from my existing libraries and didn't consider swapping them out (as in, initially it didn't even occur to me).
In some cases I found far better libs that were more actively developed (eg I ended up using xlsxwriter for my excel stuff and it was way better than my previous solution).

ps I believe they like to call it "Wall of Superpowers" these days :)
