I used to move heavy tools for a living- we routinely drilled a 1/2” hole 2” from the top of a 2x10 exposed ceiling joist in basements with a 12 foot span and hoisted 1100 pound lathes onto their floor stands from one point.
For eyed lags or hooks, pre drill perfectly in the middle of joists to just under root diameter and add a dab of PL premium to the hole, but wax the fastener if you ever want to get it out- this consolidates the deformed fibres the screw threads form and adds pullout resistance. Four GRK structural fasteners to a bracket spanning two joists is much better than one big lag if you have that option.
