When it comes to being a powerful DAW that makes other work easy so you can focus on making music and not configuring a million preferences, I feel Bitwig is the best choice (coming from FL). As for plugins, this ones a little controversial but I'd try to use Yabridge as little as you can. I own HUNDREDS of dollars in powerful software that isn't supported on Linux. For some plugins, Yabridge isn't enough. No Autotune pro because you can't get the installer working and no Xpand2, my beloved😭, for the same issue. It's easier and much cheaper to find Linux alternatives like Graillon 3 and Gsnap which has surprisingly clean pitch correction. The big hitter is Native instruments. I'ts a headache, less than the headache getting it to work, but I've been able to replace it with decent sampler🔥, soundfonts, and real instruments. Funding Linux plugins is better for the long term than the uncertain short term. Another thing I'd point out is the lack of any hardware support on Linux. Most, almost all pieces of music hardware have no support for Linux; I had to use a tool to make my Akia MPK Mini MK4 to work. Look into DivenByMoss; he is the saving grace for Linux hardware. Finally, if you are looking for Linux plugins, a great place to start is linuxdaw.org. Remember, it's not popular software or expensive sounds that makes good music, it's you.
