Hi @eruvalca,
Glad to hear that you managed to solve your problem.
Related to your request, what do you mean by “this same tutorial but with JWT instead of cookies.” Are you planning to call an external API and need an access token? 
In this case, I suggest using the approach outlined here
For the Blazor Hybrid MAUI app, you should combine the approach explained in this article with this one. Be aware that the first article does not use the new MAUI SDK, but you should because it simplifies a lot the code. I need to find some time to update it sooner or later
