I am big into grilling. Here are my suggestions:
1. Pellet grills: I have a Traeger (Junior Elite model with the Digital Thermostat upgrade, just under $400 shipped). It's pretty awesome. It's basically a convection oven with smoke. Pretty much everything comes out tasting good. Although they got outsourced to China apparently & a lot of people switched to Green Mountain Grills, and you can get stuff like Wifi built-in on those models:

If you have a large budget, Memphis makes high-end pellet grills. My dream grill is a built-in Memphis Elite, although it costs more than my last used car haha:

2. Gas grills: Weber is the gold standard. They work well & typically last a long time. I had a cheapo Home Depot one that worked well for a season, but never really got super hot. I liked the convenience of gas, but I'd definitely get something better like a Camp Chef (+1 for versatile accessories!) like you did if I were to get one again. Again, if you have a budget, Fire Magic makes really awesome ones for $$$:

3. Charcoal grills: If you want a ceramic, either Big Green Egg (TONS of accessories) or a Kamado Joe (my preference). As mentioned earlier in the thread, they have their pitfalls, but they are also amazing for a lot of stuff. For a standard charcoal grill, I would recommend upgrading to lump charcoal (burns hotter) & getting a Weber Performer ($400), which has a gas ignition for convenience, as well as a really nice cart. My $80 Walmart charcoal grill (which I actually love, but they only last a couple of seasons) is on it's last legs & that is what I will go with as a replacement:

4. Flattop grills: I have a Blackstone flat-top, which is pretty good (cast iron, although it doesn't get as hot as I want - 450 to 500F max temps typically, and I want like 200F more), but I'd get a Tejas if I had to do it all over again (similar to Camp Chef but a little more DIY & piecemeal). Camp Chef of course has a lot of accessories & versatility. I love cooking on a flat-top because I can make breakfast for everyone & their dog (eggs, pancakes, bacon, and sausage all at once), amazing sandwiches, and I just got a two-pound grill press for doing smashburgers & paninis and stuff. Plus it's pushbutton gas, so it's just like letting an oven preheat. There are some outdoor Teppanyaki-style cooktops available as well from places like Cook & Dine and Twin Eagles too.
5. Pizza grills: Pretty much Blackstone is the way to go if you don't want to jump into the grand-plus price category. I'm planning on picking one up this month as I have been getting back into pizza hardcore & doing it in my oven is heating me out of my home (500+ degrees indoors in summer, ugh!), plus the Blackstone gets up to 700F, which gives a much better crust consistency. If you're already invested in the Camp Chef system, they also have a really nice pizza accessory. There are some other models as well, but after digging into it, the Blackstone is the way to go for the price (~$400 shipped with a rain cover). Lots of neat models as you get into the $1k range too, or go the DIY route with a homebuilt wood-fired oven:

There's some other neat stuff floating around too. I recently picked up a Namath Rapid Cooker, which is basically a salamander grill. It's pretty awesome. Twin Eagles makes a beefier one, but it's nearly two grand:

Everything has specific uses. Like FiLeZz said, pellet grills are great, but not so good for stuff like burgers or steaks because it's more like an oven than a grill. Charcoal tastes the best for burgers to me, but it's also sometimes nice to have the convenience of gas for a quick meal. I cook at home a ton, so I've ended up investing in a lot of equipment over the years as my cooking skills have improved, and also based on my situation. I have a tiny kitchen & having the big old Blackstone cooktop is really awesome for keeping the heat out of the house & also cooking a truckload of food at the same time. Same deal with the pizza stuff, if it's something you're into then you can get some pretty amazing tools these days without having to spend three to five grand on imported Italian specialty ovens to get stellar results.
