I can't comment on bicycle_road, but as for cyclestreet the wiki gives a
fair description:

All other tags like maxspeed and overtaking:motorcar are useful, but
tell the consumer nothing about the inherent nature of the cyclestreet,
which is a shared road that is by design bicycle-friendly. This goes
beyond taggable properties (e.g. traffic flow to and from such streets
in the broader city grid is taken into account, there are no speed
barriers that are bicycle-unfriendly).

The tag cyclestreet=yes can serve some purposes I can think of:

* Rendering these streets differently on (cycling) maps (like a blend
between a normal street and highway=cycleway)

* Prefer them in cycling routing engines over streets lacking cycling

* Penalize them in car routing engines

It is analogous to highway=cycleway: you can easily use highway=service
and add a bunch of tags making it a cycleway in terms of access rights,
but a cycleway implies much more than that (like safety and
suitability). The cyclestreet=yes tag is similar in this respect.
