You can still build it with whatever you want to. User's don't care if you used React through a GraphQL API talking to Microservices that sits on an instantly scaleable AWS infrastructure. These are technologies designed to solve problems that Really Big Companies have, and that most of us bootstrapping a SaaS do not. Don't be worried about "Scale" either, seriously. VC funded unicorns care about scale because they have million dollar budgets going into advertising, the reality for most bootstrapped SaaS and even mid-sized businesses is that a simple dedicated host is going to serve you well. Depends on the type of business I suppose, but if you need quick bursting scale then you'll probably know it. The bleeding edge is a mess. You want to pick only the things you absolutely need from it, and if you can't figure out what it is you need, you don't need anything but what you've got and life is good. Many of these technologies come at a cost to overall complexity, and for big companies they will have enough developers to specialize in all the different technologies going on. When I'm working with clients we can often use some new fangled technologies to help in really specific areas. But the vast, vast, vast majority of clients just need you to send their user a gosh darn web page and process some forms. Render your template, cache the thing and send it over. Instant low latency web experience, hoo-ray we're all happy.
