I’m fairly knew too (I tied some bad flies in my youth, but after a few decades gap - I enjoy tying again with great renewed interest).
I’ll second the Walt’s Worm and Zebra Midge posts. Some other ones I find easier (with success at the stream) include Foam Beetles & Ants, Deer Hair Beetles, and Peacock Spiders (which have proven successful with panfish). After tying a few of these flies, I experimented with my own dry fly that worked with both trout and panfish.
I’ve taken two group fly tying classes that were inexpensive and very helpful. Contact your nearest fly shop to see if they offer classes. The other valuable resource has been the internet: there are all kinds of YouTube videos that are amazing and helpful. In addition, I attended the Fly Fishing Festival in Boiling Springs this summer and picked up a lot of tips from the presenters. Keep an eye out for future opportunities like this in your area (if they are available- I’m fortunate that these resources are close to me).
