Choice Paralysis Help

As the title says I could some help choosing my first army. I finally saved up enough money to start after a couple of back to back life emergencies. I got my start in the universe with the launch of Space Marine 2. And I have been reading and watching whatever I could find for free or cheap since then.
If it helps I typically play aggressive mixed (guns and/or magic) damage brawler/bruiser types. I like to get into the fight, hit hard, and take some hits, but still have some kind of good firepower for when I begin the attack or can’t get close enough. I have already have an eye on Space Wolves, Blood Angels, Custodes and Chaos Space Marines (Black Legion) Any help narrowing it down to a single army would be appreciated. TIA
