Locktime: you can set the locktime on your transaction so that it can only be included starting from the block N + 1 where N is the current block height. This way your transaction can't be included in a block with the current block height.

Reorgs: now I don't get you at all. I conjecture there might be confusion of reorg as in 51% attack scenario with greedy miner reorg (no 51% power). In the latter case the miner gets the coinbase reward anyway, so why does the coinbase size even matter?

Unless I misunderstand locktime, I don't see how either of these points is going to deter greedy mining.  There is no need to reorg to have less fees, as plenty of new transactions are always percolating in. Likewise, locktime doesn't materially affect miners - the coinbase transaction will still sum to the same value and the winner will eventually get the sats.
