Yep, my mistake.

5% of c = 15,000km/s or about 420 G-hours using all thrust to accelerate.

A reasonable compromise which folds increased capability/efficiency with
Tech Level.

Doesn't get around the power problem, though.
All those terajoules of KE per kg vehicle mass have to accumulate somehow.

Rupert's idea of the cosmic microwave background serving as a reference
is a good one.

Local star as the preferred frame makes sense for in-system travel but
has consequences for relativity, as you point out.
