Scratching the basics, questioning my path forward

Hi all - I hope you are having a wonderful Sunday. A bit of background about me, I started to learn trading couple of months back. One I had decent grip on the basics, I started with demo account to see how it feel and understand practicality of trading. So I far, I am able to grasp few concepts while other are lost to me. I started DEMO account for CFDs on forex. I am based on UK. Recently I have been questioning instruments to trade or atleast start with? There quite alot i.e. Forex, commodities, indices, stocks, options, crypto etc etc. I am considering factors like trade timings, options to scale (especially without putting in bulk of your own money), availability of good brokers in the UK, practical for newbie traders to start with etc etc. Would love a perspective from this community on what they trade and why? What are the pros and cons? Any recommendation on how do I select one?
