Two dummy questions about Unicode

Two little curiosities about what makes up the Unicode standard.
1) Why are there glyphs like <o + tilde + acute>, but not <o + tilde + grave>? True that. if necessary,  you can create and insert maybe in the PUA or leave them unmapped, but I don't understand if there are linguistic, graphic or other reasons that determine the presence of some composite glyphs and other ones not.
2) In the case of mapped glyphs, there is the possibility to call them by name (Abrevedotbelw) or simply indicate them with the code (uni1EB6). Are the two modes completely equivalent or is it preferable to choose one?
