Welcome, I've certainly seen far, far worse from a newcomer to domains. At least all of yours are recognisable and despite it being a dot net 'smartstrategy' would be my keeper. Plenty of businesses out there using the term and if a business is based purely around selling a complete business internet presence, they might not be too reluctant to go with the net.
You've clearly got your direction right. It's just a case of finding that appealing combo. I certainly wouldn't consider out bounding these types of domains UNLESS you can identify businesses with the exact name Without any Trademarks.
Keep your prices low and appealing, a few hundred dollars or so
