North British Warrior

Yuk ... doesn't do it for me

In what way? Not accurate enough for you?

See, this is the problem. "Arthurian" is a popular term because of it's romantic associations, much as 'Celtic' and 'Viking' are, despite the fact that nobody referred to themselves as being either Celts or Vikings.

Depends what you want then. A basically accurate but unromantic term or something that...does it for you.

Post Roman Britain and Europe doesn't work because if you CAN define the point at which Britain becomes 'Post Roman', the same date can't be applied to Europe.
You can't even have one date for post-Roman Europe on it's own.

Whilst you can apply the same argument to a term like 'Early Medieval' it does at least put the period at the start of a new 1000 year period in European history, rather than consigning it to the fag-end of the previous one.
