Upon further research, going to need to revise some of these recommendations. Would be better to use the_geom_webmercator and some trigonometry for distance calculations and so on, rather than casting to ::geography. Will allow use of meters units, while also engaging the default geometry index on that column for better performance, while also being the most accurate considering our data is local to a city and not global.

@andrewbt regarding L306, it looks like it does use GeometryFromText. So are we good on that one?
