You're not wrong. As fan of single-storey (your "normal") "a" and "g", a few additional examples do, however, come immediately to mind:
Classic example: Futura.
Modern examples:
Apple fonts: Monaco uses both single-storey "a" and "g"; San Francisco uses single-storey "g" by default, and includes single-storey "a" in stylistic sets.
The Adobe Source (Code, Sans) and IBM Plex (Sans, Serif, Mono) font families include both single-storey "a" and "g" as alternate glyphs accessible through OpenType stylistic sets.
