New to espresso and looking for bean recommendations

I have had an espresso machine around 3 weeks now and trying to try some different beans.

I started with 2 different Colombian medium roast beans but found them a bit too ‘tangy’ for my liking.

I have tried some beans with chocolatey/biscuit/malt/nut notes and found I tend to prefer that.

Now I’m staying away from anything described as fruity but not sure if I should be doing that or trying some other fruity beans from different areas.

Any recommendations would be great, I’d love to try some of your favourites to find what I enjoy
