It's always possible to start at a higher level and there's nothing wrong with that. Bandwidth is everything! But Dave has videos where he explains that other features are right near the top. Channels, decoding, measurements, decent UI, all these are part of the equation.
OTOH, you can go a long way with electronics with a lower level scope which means you have money left over for other things: Signal generator, soldering station, power supply, etc. Few people can afford top-of-the-line models for everything.
Probably the fastest selling scope around is the Rigol DS1054Z which, when unlocked, provides a decent bandwidth of 100 MHz, decoding of various serial protocols and more measurements than I know what to do with. It's a great scope to start with.
There are better scopes! The thing is, anything that has much better features costs 2 to 3 times as much. There is a new 200 MHz Siglent (dual channel) that may make some headway against the Rigol for the entry level kind.
There's a lot more information over on the Test Equipment forum. Lots of opinions on beginning scopes and features.
BTW, you buy the Rigol DS1054Z and decide a few years down the road that you want a $2000 scope so you sell the 1054 for 1/2 price and you have gotten several years worth of education for a couple of hundred $. By then you will know exactly what you want.
Or, you will come to the conclusion that the 1054 will do everything you need.
Still, there is no substitute for bandwidth and 200 MHz is more than 100 MHz. Remember, for square waves, the fundamental frequency is only part of the waveform. You need to be able to get to at least the 5th harmonic and the display is better if you can get to the 7th (and so on out to infinity).
A 200 Mhz scope may realistically display only a 40 MHz square wave. A 100 MHz scope can only do a 20 MHz square wave. Bandwidth is king!
I still have the 350 MHz Tek 485 that I bought about 13 years ago for about $200 on eBay. It has no features whatsoever but it has bandwidth. I added the 1054 to get features I never knew I needed - especially single shot. There is no comparison of features between an analog scope and a modern DSO.
I use them both!
