Basement Waterproofing a Basement that has Structural Clay Walls Using Weep Holes

I'm curious about any distinctions that exist between the swale + pond idea vs. French drain + dry well idea. The swale + retention pond sounds okay but it also sounds like it would be the most disruptive to a yard without providing the more efficient medium to transfer water. One difference I can see as being better with the swale + retention pond idea is that the final point where the water ends up would be open to daylight and more likely to dry up faster whereas a dry well would likely retain water longer due to its encapsulation and less air movement, etc... Both benefit from percolation, which is an issue with my yard due to it consisting of clay loam... Regardless, the swale + pond would require my yard to undergo major landscaping. I'd have to take down a tree over in a corner in the front yard, perform some massive grading with the dirt, then install the actual swales + pond and that would be only the front yard (albeit the area which would benefit the most from something like this if it does anything at all). However, with a dry well--assuming it's fairly close to the same functionality one gains with the swale + pond--would be completely hidden under the ground and still enjoy the drainage you'd observe with the swales emptying into the pond, only better because it would likely use a more efficient drain line with tarp and pea gravel on top of that covering the pipe, etc. With all these ideas being floated around, I'm almost tempted to consider taking tons of my yard out to be replaced with a better more percolating dirt in an effort to facilitate better absorption, only at a grade to motivate the absorption away from the house... I shudder at the cost of something like this. But again, the pond idea would benefit from daylight + wind movement, thereby increasing the likelihood and speed of drying, or at least, I'm assuming... I'm just not sure what to do and I'm worried that I'd just be chasing my tail with these suggestions. But whether anyone on here likes it or not, I'm definitely doing an internal drainage system before I do anything else as part of that project is going to entail joining my two sump pumps together via the trench to incorporate redundancy that I don't currently enjoy. In other words, right now, my perimeter drain pump is on it's own circuit. So this drain system will join the two so that if one goes out, the other one can keep the drainage going. I've got 2 water proofers and a plumber coming out to the house next week with another construction guy who did my 2 basement wall rebuilds coming out sometime after that. I plan on asking them all about these ideas to see what they say. I'm afraid they'll poo-poo it and say that it's unlikely to do much for me, especially considering subsurface water issues I have (i.e. - high water table). Not saying they'd be right to poo-poo it, but just saying that this has been a common reaction to similar ideas when they're floated to these kinds of guys that have been out to my place before to talk about things like this.
