New to wordpress.

Hi, I'm new to wordpress and I'm trying to wp from localwp. Trying different plug-ins and watching YouTube to learn about how to. But a lot of people there suggested to go with astra theme and when I'm in reddit I saw people talking about getting to know wp default 2024 and something fse I don't know what it exactly is. But can someone suggest a right path to go through. Yeah, I know there r a lot of same questions asked but something is different in all so I just asked to get some new ideas and all. Thankyou
