I believe most clovers are better P scavengers than buckwheat.
Buckwheat is known as
a “phosphorus pump” because it is assumed the roots
solubilize phosphorus from phosphate precipitates in
the soil profile and subsoil. The following characteristics make it outstanding for its phosphorus efficiency:
1) a finely divided root system with a high ratio of root
surface to root or shoot length; 2) a high storage capacity for inorganic phosphorus; 3) an increased release of
protons and solubilizing substances by phosphorusdeficient plants; 4) a favorable ratio of phosphorus
uptake to root mass growth, especially at a low phosphorus supply; 5) a high activity of acid phosphatase in
the rhizosphere and the capability to use phosphorus
from organic sources (Gardner and Boundy, 1983).
Buckwheat has poor response to nitrogen fertilizer due
to its short growing season (“Crops of Other Plant
Families”). It has a higher tolerance to soil acidity than
any other grain crop (“Alternative Field Crops

It looks, from when I transplant blueberries, like they have very shallow fibrous roots, so I do not want to potentially crowd them with the shallow peppermint roots.

Not only that, but buckwheat is one of the best phosphorous accumulators out there and fruit bearers need it especially.
