The concern is "Does your building block work in a striking environment (or just work in a wrestling environment)?"
The entering strategy can affect the technique. For example, what's the point to train a "hip throw" by wrapping around your opponent's waist when his free hand can punch on your head? If you use underhook instead of waist wrapping, your opponent will have no free hand. So how to achieve an underhook can determine whether your hip throw will work in a striking environment or not. Of course if you only concern the wrestling environment that striking is not allowed, the waist wrapping will not be an issue.
Another example is to pull on your opponent's back arm while scoop his leading leg. This is very difficult to set up. But if you push on your opponent's leading arm and back fist his head, you will force him to block with his back arm. this way you will have chance to pull his back arm.
IMO, if you don't try to use your striking to set up your throw, your throwing skill will be hard to apply in a striking environment.
Here is an example to use punch to achieve an clinch, and then execute the throw. You move in through an angle to avoid body spinning.
