I think it would be useful to provide for these names to be registered like company names so that no other group can use them.
Won’t work. Either you’d have to force the different major branches of Christianity to squabble over who gets to call theirs “marriage”, with all of the other relegated to finding a new name, or you’d have to grandfather in the term “marriage” to apply at a broader level than a single sect, which leaves you in pretty much the current situation.

Not necessarily. they can all use marriage but precede it with their denomination" Catholic Marriage; Baptist Marriage: etc. After all, that is all thy have the power to do.

Who’s you and why does you care?
When Mormons marry in the temple they call it a sealing because they view it as persisting after death (whereas typical marriage ceremonies use the “’till death do you part” language). Do you really think that causes problems?
