I would say TinySA and NanoVNA are definitely worth the money and so cheap that you don't have to think twice.
But they are complex devices and you have to learn a bit.

Of course you get better devices for more money, but with these two you have enough to do for a start.  ;)

When working on a specific digital protocol, particularly complex ones like USB, protocol decoders can be very useful.

Probably not relevant, but VNA is an impressive instrument. Most of them are very expensive, not very easy to use, but I learned a lot even trying to use a simple one, so I also +1 to simple ones like NanoVNA just for what can be learnt from it.

It might not be a need now, but I also +1 to current and differential probes. If you are interested in the power usage, there are relatively new, simple and cheap source measure units for microcontrollers. Source measure units are usually quite expensive.

LA wont record analog signals

So it allows you to record for multiple seconds or even multiple minutes of traffic. So no need to trigger on the area of interest and keep rerunning your test, you can just record it all and then scroll trough it at your own pace. Looking trough this much data is much easier with a mouse as opposed to knobs on a scope. So for that reason i prefer it when looking at something like a SPI or I2C sensor or picking apart a UART firmware update protocol or something.

This is the reason I bought a DS Logic Plus LA.  Decoding on many 'hobbyist' scopes is often limited to what can be displayed on the screen.  In addition to longer captures, a decent LA also offers more triggering options like pattern, cmd or address matching that can help locate data of interest.

What is a good logic analyser? Surely the $10 can't be that good
