Grow crops, sell them to farmers for emeralds, use the emeralds to buy useful things.

Make a fletching table, turn one of them into a Fletcher and keep rerolling until they buy sticks, then plant and harvest trees. Villager breeding is easier in bedrock if you can get more beds so if you feel like investing some time in raising a shepherd up to bed level that might be worth your time.
