There is only one closing strategy you need. James Muir covers it in his book "the perfect close".
Far too many people, have a vested interest in making closing, or any part of sales as difficult so you hire them. They sell you consultancy.

Invest in yourself.
You have done all the hard work to prospect for business. Then, you tackled landing a meeting. You listened, overcame objections, and explained the features and benefits carefully. Now, it’s time for the close—the make-or-break moment in the sales process.
