The bolded parts are like the SLI Te I know but I guess we can't conclude many things from this. I have focused on SLI because it's the type I know better.
I think if you're sure of your type, you'll probably know and understand what Fe is and can easily spot it in people who value it. Same thing for Fi.
And this:
"ISTps can often hurt the ones they love. Why would you want to do this? The one way to understand your feelings towards the loved ones is by hurting them and watching them suffer, only then you can be sure of how much you love them. Sounds cruel, but unfortunately this is the strange nature of this particular type of hidden agenda, which cannot be used as an excuse for such behaviour."
I think this behavior is number one indicator of someone being ISTp from my experience (when you're becoming close to them).

The only LSI I've met, was also not so into tests and all that... he was a workaholic, I felt that he was hiding everything about himself. He can sometimes out of nowhere say affectionate things to his friends. He was also so confident and polite... So yeah most of what you said about your SLI/LSI apply here.

The differences I could think of:
ISTps are unpredictable unlike ISTjs.
ISTjs may be harsh and controlling while SLIs are more gentle and forgiving.
ISTps are generally relaxed, even though SLI-Te at first may look grumpy and angry, but when you get to know them, they're easy going and laid back.
ISTjs have a hard time taking a break and they are more likely to be workaholics.
