Is it time to move on or can change be implemented?

Long time lurker, first time poster. I'm going to keep this question fairly vague as I know some of the team that I work with is on here as well.

Without getting too deep into company details, we're in managed services, specifically to do with online advertising.

Over the course of a few months we changed up lead flow, rolled out a new marketing plan (this part within the last 1-2 months). in order to better align with our overall operations strategy. However this is coming on the heels of some absolutely stellar months, which are now starting to slow. A huge portion I believe due to the changes we made now trickling in (our sales cycle is often sub 30-days, but up to 90 in some instances.

Now we're in a position where the new marketing plan doesn't seem to be "hitting" as hard as the older version and ultimately we've seemed to really pigeon hole our strategy into a one size fits all box.

I enjoy everything about the company, but it seems like with the growth we've had we're heading in a direction that may ultimately not match the market due to our higher than market cost, and currently rigid offering.

While this is a bit of a long rant, I wanted to give context to ask two higher level questions.

1. I've used a bit of SalesForce data to point out that win rates are steadily dropping, but was countered with contract values going up. Has anyone had success trying to re-steer the ship in a different direction by leveraging what they are actually seeing on the front line versus what SalesForce is telling you? I.E. With this context does anyone think there's a possibility of traction from a senior (to this company) sales rep?
2. Should I abandon ship and look elsewhere? Making solid money this year and the most I have made in a single year in sales, but ultimately IDK about the directionality and it seems like our operations side is putting more "parameters" in place that's making it harder to sell.

For context, our sales team is under 10 people.

Any feedback is appreciated and I would be happy to elaborate on some context where I can while remaining anonymous.
