Being trained in typography is like a curse. You will suddenly see all the mistakes and amateurish design decisions everywhere, and you will hate them.
On the other hand you can create something that looks good in 5 minutes.
Would you be able to recommend resources on learning towards becoming somewhat trained in typography? Beyond blogs and coursera courses, where might one start?
Typography is one of those ancient skills that's so well covered you can't go wrong anywhere you start. The only problem would be if you needed a class room environment or a one on one instruction. If you're a self starter then (as cliche as it sounds) launch off the wikipedia page : https://en.wikipedia.org/wiki/Typography
There'll be tons of instructional websites too. This is a 600 year old art that hasn't fundamentally changed its terminology. Anything on the nerdy to practical spectrum of knowledge is out there for you to grasp.
Look at open source fonts, study how they are created, and which components are frequently updated, and create one of your own. It's much harder than it seems. But definitely do-able.
Typesetting is related and has a similar effect. Being able to spot every document authored in Microsoft Word and its, frankly, ugly decisions is not that fun.
