I’d start really simple. A good burr grinder and either French press or pour over. Personally YMMV on French press vs pour over, but I tend to enjoy the taste and feel of a pour over coffee. If you have a set budget spend as much as possible on the best quality grinder. You’ll notice the biggest difference in taste, texture and brew from a grinder (IMO).

Also, buy a scale. You’ll want to start doing everything by weight now. I’m sure people can give you way more in-depth responses than mine, but this is my easy slide in to the world of coffee brewing. One day you’ll end up like the rest of us buying $6-700 single dose grinders and trying to math their way into the best cup of coffee every morning. It’s a lifestyle choice for sure.

Editing to add this bit:

I forgot to stress something I feel is the most important. It shouldn’t be a struggle or you shouldn’t really feel like you’re having to do a ton of work for your coffee. Yes boiling water, weighing the beans, grinding, then timing your pour and weighing the whole thing is work, but don’t stress over too much of it. It’s about enjoying the coffee and how it tastes. I feel like so much of this “hobby” or addiction gets wrapped up with sounding like a ton of work. It shouldn’t be that way, and adding one big piece each time slowly over time adds up to almost nothing.
