Is there a resource geared towards people like me, ideally something like https://pythonforbiologists.com (it's how I learnt python in the first place).
For learning the language, I'd honestly say just check out the manual, it's really nice: https://docs.julialang.org/en/v1/
I'd also encourage you to check out the Julia Zulip https://julialang.zulipchat.com/# and Discourse as two great places to engage the julia community.
Both of these places have a lot of traffic from some of your fellow bio-informaticians as well as lots of other domain experts and are very welcoming of new language learners.
It's a bit out-of-date, but still useful.
