Find out first what size and fit of frame suits you now which might be different to what fitted you back then and don't do what I did on my return to cycling 25 years ago and buy a newer version of the last bike I had as a teen which was a 10 speed racer, I ended up changing just about every single component on that bike to get it how I wanted it.
There is nothing wrong with a good cycling midlife crisis, I am thoroughly enjoying mine.
