Lots of great suggestions and information so far. I have been homebrewing since 1992 so be careful, it can be addicting and expensive and also a lot of fun.
You should definitely consider finding a homebrewing club in your area. I belong to two of them in my area and have belonged to a total of 4 over my lifetime as a brewer. If there's a homebrew supply store in your area those usually have info on local clubs and imo it is a good idea to support local businesses. You can also find clubs using the AHA website: https://www.homebrewersassociation.org/ ... brew-club/
Our clubs will periodically have brew days, either at a member's home or at the local homebrew store where you can see and talk to people who are brewing. I've brewed at those at least 5 times and I also hosted a brew day at my house a few years ago where 5 batches were made. Seeing how the process is done and asking questions will help you understand some of the voodoo in brewing.
Personally I brewed one extract batch back in 1992, mainly to see if I wanted to continue brewing, then switched to all grain using something called an easymasher. About 7 years ago I built a single tier, 3-vessel, natural gas powered, PID controlled HERMS system but I also like to use brew in a bag (BIAB) sometimes for simple single infusion mash recipes. BIAB can be done with a single pot and single heat source and doesn't require a pump though imo they come in very handy.
To avoid boilovers, especially if brewing inside, I recommend using Fermcap or its generic equivalent which will drastically reduce the foam on top of the wort that causes boilovers. This could possibly save a marriage if you are brewing indoors on a stove top.
Besides cleaning and sanitation I think one of the main keys to good beer is controlling your fermentation temperature. This can be done a lot of ways but personally I use a chest freezer with a temperature controller. I built my controller but they have come down in price so much that it almost doesn't make sense to DIY them any more.
Another longer term enjoyment factor is moving to kegging as opposed to bottling. When I built my brew system I also build what is called a keezer (chest freezer made to hold kegs with taps in the side). Mine has 4 taps and holds 5 kegs and it is a joy to use as opposed to the few batches long ago that I bottled. If I want to bottle for a contest or club meeting I can do so easily from a keg.
I actually started kegging with a single keg back in the 90s using a DIY jockey box (a small ice chest filled with ice with a tap in the side and a cooling plate that beer is run through to cool the beer) for at least 10 years before building the keezer.
If you are looking for brewing equipment of course you can buy new but there are always people leaving the hobby so checking craigslist or FB marketplace or the homebrewtalk.com for sale forum can sometimes get you a bargain. A friend is currently selling his propane 3 keggle system which I know he has at least $500 in for $250 and would probably take $200. If I didn't have too much equipment already I would buy it myself.
As you get farther along in brewing I think brewing software can really make a difference in both enjoyment and effectiveness of the hobby. I invested in Beersmith many years ago and have continued to use it though upgrades but there are now many alternatives including some good free and open source ones. After using DIY spreadsheets for about 20 years brewing software has made the recipe planning and recording process a joy instead of a necessary evil.
