I occasionally use gw2taco, which is very good with some of the third party marker packs for helping through content I find more annoying than challenging, such as a couple of the jumping puzzles. The utility would have been fairly marginal - I like waving at people and a couple other things, but I don't use emotes enough to really care. Unfortunately, it did not work for me, and so I am not motivated to try again. I tried, but do not use, an addon to offer a similar menu for emotes.

I don't want to try and find five (or even three) buttons on the mouse, so one button for the menu is great. I find this vastly more convenient than key bindings, as there are no convenient key bindings left on my 16 skill characters, without either letting go of the mouse, or moving the hand from the movement and skill keys. I use, and would recommend, the 'radial mount menu' addon, which allows me to use a side button on the mouse, plus movement, to select a mount. It also tends toward provoking an unhealthy focus on damage output rather than mechanics, which is ultimately not a great way to perform your best. Most players do not benefit from it, and it is technically fiddly, so you shouldn't use it unless you have to. It isn't good for 'discovery', but it is good for when you want to navigate fast.

I personally like gw2navi - the overlay - for providing GPS style guidance for a bunch of things.
