Yes, Fertilome Over the Top II can be used over cactus/suculents.
Fertilome Over the Top II is a grass killer so it will bermudagrass and tall fescue grass.
Bermuda would be considered a grassy weed, so you need a product that is geared towards grassy weeds and not broadleaf weeds. We want to be clear that bermuda can be suppressed, but it is VERY difficult to kill completely. It will take multiple treatments to finally kill it. But Fusilade II is usually the go to product for this issue.
This is directly off of the product label:
Apply 0.07-0.14 oz/1000 sq. ft. (3-6 oz./A) along with 0.25% v/v (1/2 pt./25 gals.) of a nonionic surfactant. Application should be made every 28 days when the grass weeds are actively growing. The higher rates may result in temporary discolorization of the desirable turf with recovery in 10-14 days. Do not apply to desirable turf which is under stress. For best results, make applications in spring and fall and avoid treatments during July and August.
Complete control of undesirable grass may take 1-2 growing seasons.
We also recommend calling your local county extension office as they usually know the optimum times for spraying lawns in your area.
