Solid core wires are typically preferred in any electrical installation, especially those dealing with RF. For the record, digital data is an RF signal.
The only reason that stranded wire is so common is that it is far more flexible and less prone to damage from movement. Stranding introduces all kinds of "weird" things such as stray capacitance, "strand jumping" resulting in unequal signal paths at various frequencies, time smear, etc...
There are differences amongst various designs that try to deal with these problems. Some use network's, some use multiple strands of small gauge solid wire that are individually insulated, etc... Large gauge solid wire has problems of its' own, especially when used as interconnects. Sean
