I believe civs can be given tiered biases, so if the first is unavailable it will place by the second. I'd suggest the river is more important to the civ overall (the sea beggar feels very disconnected from the otherwise peaceful, trade, gold, culture focused civ)
On the other hand, rivers usually make for "fertile" land which means starting locations. If you give them a coast bias they might get both fairly often, whereas if you give them a river bias they might end up nowhere near the coast. Also fresh water is pretty common so if you start near the coast you will almost always find fresh water, but the other way around is less likely.
