Family office/silent investor vs. VC and bootstrapping. (I will not promote)

A family office is interested in investing in our startup and giving us basically as much or even more than we were asking for to close our round. They’re a family office that prefers to invest in startups than pay taxes and expects a 2x return within 5-10 years. They’re not tech ppl and don’t have any interest or ability to help strategically and basically just let you do you. I’ve been wary of VC bc of their need for 10x returns and tendency to liquidate companies if they’re not on that trajectory. So I was focusing on only angels in our first round but was struggling to finish with small angel checks so this seems like it might be a great alternative and can pretty much provice everything we need without the downsides of VC. Am I missing something?
