Hi. I don't think either are trending. I believe it's more a matter of taste and lifestyle. Glass tops are a bit more high maintenance as you see smudges much more easily.

'Supreme" chairs come in dazzling colors.I flipped for them when in Kerala but bought them while at Vijayawada. They are available anywhere and are water resistant, strong and too cute to look at. I am yet to find a table to pair them with but will do so soon. red,lime green,black,white,brown,blue,yellow...my god.The colors and their vibrancy is awesome.Many more colors as listed are available.

Since you already have an exposed brick wall that you are working on you can try to give this space a subtle industrial look, some photos to inspire you: Do consider adding pendant lighting, you can also give it a chic look by mix and matching metal chairs! Hope this helps!

You can get a custom wall art done , glass with bronze, glass painting, that wall should be a center of attraction, anyone walks. I have done this for a site, it works wonders, guest appreciate a unique feature. this can be done as DIY project on weekend also. these are some some real world executed ideas. cheers mate.
