Miners (that is, the full node building the miner's blocks - which may be a pool) decide what they put in blocks.
Reasons for including more transactions:
- Earn the fees of transactions included.
- Make the Bitcoin on-chain ecosystem more useful.
Reasons against including more transactions:
- Larger blocks propagate more slowly through the network, giving them a slightly larger chance for being reorganized (as a competing simultaneous block may win).
