Instead of building the query twice, it's a bit cleaner to build the params dynamically. Something like this:

var params []any
if len(poolIds) > 0 {
  params = append(params, cbor.Set(poolIds))
}
query := buildShelleyQuery(
  currentEra,
  QueryTypeShelleyPoolDistr,
  params...,
)

currentEra,
QueryTypeShelleyPoolDistr,
cbor.Tag{
Number: cbor.CborTagSet,
Content: poolIds,
},

We have the cbor.Set type that handles this
