First off, you can shrink L so much as you increase C at a given frequency f_RES.
Choice of integrated L value is primarily affected by 2 criteria:
1) Effective tank conductance G_TK varies inversely as L
So, larger L=> larger Q_L and  lower G_TK

2) phase noise L(Δω) varies directly as R_L, the series resistance of the inductor
larger L=> larger R_L and poorer L

It follows, largerL=> lower power consumption, lower f_RES and  f_Q-PEAK, the freq at which Q peaks.
So, we choose  the largest L having peak Qclose to the operating frequency
