Fewer font sizes and more font weights in general is always good.

Removing borders is extremely powerful for a lot of great reasons. When trying to maximize data density and readability, when trying to reduce clutter/visual noise and gain whitespace. The use cases for borders can often be resolved in other ways. However this puts more demand on the quality of the typography and layout hence the other techniques mentioned come into play those are design challenges worth addressing.

More on borders: This of course is a tool that can be mis-used but I find it is one of the best tools I have. The emphasis should be on data / information not on arbitrary borders. You can say the same thing many different ways visually. This is under-appreciated. You need not have font size, color, style all colluding to say the same thing, that you can accomplish with only one of these. When dealing with any series of items the human eye will clearly see periodic patterns and implied lines / alignments very quickly thus I find that often borders are unnecessary and even impede a working design.

A key observation is that with every border you have two white space areas to design with and a foreground element competing for attention with your actual information. Every border you eliminate gains you twice as much whitespace as you had and one fewer foreground element. 3 design components to 1. As with lines of unnecessary code, when you can delete elements in a design you are winning.
