I would be a little concerned about your 10x3 session on the Monday. You say it is for every muscle group, which makes it a very demanding workout and creates a high possibility of overtraining. If you have a look at the Waterbury Method, which I think was the first program on this site that CW used 10x3, you will see that there is only 1 main exercise per workout that uses 10x3. The rest are 4x6.
I reckon you could cycle TBT, WM and SFM for the rest of your life quite satisfactorily. You mentioned that you didn't like the change of the parameters in TBT, but you may be missing the point of the program, it is based on conjugate periodisation where all strength qualities are developed simultaneously. This is often a feature of CW's programs. There are also "back-off" weeks built in e.g. the days where there are only 2 sets of any exercise. This prevents overtraining.
I would suggest cycling through this progression: TBT,WM,TBT,SFM. This allows you to rotate between the more hypertrophy-focused TBT and the functional strength WM. The SFM would then kick in each 6 months to allow you to bump up your limit strength and perform better on the other programs. As explained in the SFM article it is only a mesocycle and is not to be used all the time.
I hope this helps.
