The OED has [this page](Oxford Languages | The Home of Language Data) and it has a fairly long list of meanings. Master as owner is labeled “historical”, which is the point. There is also of course master bedroom, which comes from the lineage of master of the house, which comes from the lineage of owner, from which words like master of a ship come from, all tracing back to magister, which is the Latin for teacher which my years of Latin remind me (vaguely) comes from having more knowledge/ownership/control of.
