It really depends on a personal taste. Even Ubuntu or LAMP/LEMP web server can be bloated, WordPress itself too. (At least for me all of this is bloated).
Regarding plugins - you can see that bloat on some - Yoast, Jetpack and maybe don’t see on other - Gravity forms. All rich featured plugins are bloated with something what you don’t use.
Another group of bloat for me are plugins which just turn off/hide some already installed functions, like mentioned HIde SEO Bloat plugin. This kind of plugins simple add additional code to your site/server. If you don’t see something, it does not mean, it’s not there. This remind me some practices how hide some frontend code with CSS.
I try to keep everything as simple as possible, anyway even with my “minimalist appearance” practically I don’t feel to fight with everything, so I have to live with some “bloat”, it can save some time (some extra function with click click model, instead of googling and coding whole night).
You mentioned in another post something about installing 33 plugins , personally I would probably don’t do it, maybe WP is not even the right tool in this project. Depend on 33 sources, there is huge chance something will break sooner or later.
I still like to see more focused - niche plugins/theme than monsters which try to do everything.
