Tides with 3 Largish Moons

I would like to have an Earth-like planet (~Earth gravity, ~Earth day, ~Earth year, and liquid water oceans) with extreme variance in its tides. I want the lowest tide to reveal about 30 miles of floodplain, and I want there to be occasional massive tidal waves. I understand that, in theory, this might be achieved by giving the planet several relatively large moons with different orbital periods, such that sometimes they are spaced out, so they balance out the tides (a kind of medium tide), and sometimes they are all together on one side of the planet so that they create a highest / lowest tide.

The star and other solar system features can be placed under whatever side conditions to improve stability, if they can improve stability.

I am building animal life cycles so that they correspond to different tidal conditions. As such, knowing the approximate frequency of high/low tides and tidal waves would be really handy.

Is there a way to set up the orbits of the moons in a stable way such that tidal waves occur predictably and that high/low tides are relatively rare? (Of the order of every 30-40 days.)

Added bonus, if you can provide any spitballed numbers for viable orbital periods and tidal patterns.
