I’ve been using the 2.80 betas for a while (and Blender itself on and off for decades) and it never ceases to amaze me how long it took them to make left-click select the (sane) default.
If you’re using a Mac with a beefy Radeon GPU (a rarity these days, but likely for my readership), AMD has an updated ProtRender plugin for 2.80 that you might want to look into (although it seems to render some materials differently than Cycles on other GPUs).
