Suitability of Meditation Types

I return to this site after a long absence due to various causes. My current question is whether some meditations are more suited to certain contexts than others, for example: 1. Would mindfulness of breathing be as easy as other meditations on public transport? 2. Would mindfulness of sight be more appropriate in such a context? 3. Is mindfulness of breathing suitable to walking, or is it preferable to practice mindfulness of stepping and so on? I am mainly asking this because my formal meditation is almost impossible, as I live at home and noises are continuously occurring. I'm specifically talking about television noises, or discussions, which in addition to being loud also distract from my practice. Thus, I search for other situations to meditate in, like transport and walking.
