Advice on the design of small parts, plus: paper weight

So I'm working on my first paperraft design, a sci-fi ship (Rocinante from "The Expanse"). The model is going to be about 40cm end to end, and has a number of small, (about 1x1x1 cm) protruding watchamacallits attached to the main hull. basically box-like pieces of differing shapes, with the bottom face missing. I was wondering on the best way to design those, in terms of how they attach to the hull. I thought of three options:

1. create them with a bottom edge so each is a completely closed surface, then glue the bottom surface to the main hull
2. Add tabs along the perimeter, fold inside and glue to hull
3. they are small enough, simply applying glue to the edges would work just fine.

What's the convention with such pieces?

Second question is about tabs in small parts. some parts are quite small, often with an acute angle between edges that should be connected, so there's either a very small tab or little room for a tab at all. In such cases, what is the norm? make small tabs? use joining strips? avoid them altogether and just glue the edges? they are small and not load-bearing in any way.

Last question has been done to death, paper weights. I searched on the forum first and in the search results, the answers hover around 80-110 grams per meter. That seems pretty flimsy to me - I haven't built a paper model in ages, and I made a terrible mistake and threw all of the one I did build away at some point, but I seem to remember they were printed on thicker stock. I was thinking 200gsm?

thanks in advance for any input!
