I think I'll go with the second(a pool that protects you from a bear market or IL) and last(the tokens you receive as rewards) strategies because they seem more sensible to me.
That's a great advantage over other platforms, easy access to liquidity and without fees.
Usually, you should combine strategies. Such as (in an ideal combination) a diesel pool where you need both tokens + you like the tokens received as rewards + a good APR.
