Drawabox seems pretty popular on Reddit. It's pretty strict in the "this is the only correct way to learn" sense. If you're into that, it may be an option. It's self-guided, but you can post to get "graded" along the way so you know where to improve.
I'd love to tell you that I went through all this in 2020 during lockdown and now I'm an amazing artist after having a story very similar to yours. However, after buying a full box (12... 20... I don't know) of the fineliners, the first one stopped working almost immediately. The second one was DOA. I pretty much quit out of frustration after that. I recently just bought a 2 pack of a differnt brand (Sharpie), thinking something from a local store may have better luck than whatever Amazon decides to send me. So I'm going to give it another go.
I have seen enough drawing progression posts to accept that drawing is a learned skill and not something you're just born with. I also think patience is a big part of it. When I was in high school, the best thing in my sketch book for art class took me several hours. I was meticulous. Usually I just want to go from nothing to something good in 5 minutes. I've seen posts from people who made amazing stuff who say they spend 50 hours on a drawing. So I guess you get out of it what you put into it.
I have aphantasia and I found the drawabox approach especially appealing and quite similar to how I go about learning a new language, a musical instrument, grasping new math concepts etc.
So, in a sense I wasn't at all surprised to find out that the creator of drawabox Uncomfortable (Irshad) has aphantasia, too.[0]
For people who (have to) rely on a lot abstract thinking, I would highly recommend drawabox.
