PBS has excellent live coverage. It might be free on YouTube but you can access all of PBS’s videos stuff by donating to them. It’s a bit of an odd process because you donate to your local PBS but their streaming service is consolidated.
NPR also has good coverage if you want to play a board game or something while still following the insanity.
There are already so many great and detailed answers here. I’ll give some short opinions.
Take a training class or go with a gun loving friend to rent some common guns. Decide which one you like the most and shoot well. Having a gun you can personally shoot well is much more important than some feature people say you must have.
Get a flashlight on the gun or to keep with the gun. Don’t put a flashlight on the gun unless you personally want to.
Get something you can easily carry all the time. The super cool full sized handgun on your desk is not as useful as the .380 in your pocket.
Spend some money. A good used gun is almost always better than a cheap new gun. Guns don’t expire and it’ll probably always be worth close to what you paid if you go to sell it.
Get a good holster if you’re carrying. Don’t be afraid to try a few and see what works. There is no right choice. It’s all about what works for you.
It’s all about you. Seek advice but do what feels right to you. The things that matter are how well you can shoot that gun and that you have it available if needed. You get to decide what that means to you.
Personally I carry a .357 6" revolver and a .380 bodyguard. As long as my pants have a pocket I can have the bodyguard on me.
If you have more specific questions feel free to ask but I would very highly recommend talking to someone in person.
