TPS7A7100 Input Capacitor Recommendation

From the TPS7A7100 datasheet (page 17 - Input Capacitor Requirements)

The best guideline is to use a capacitor of up to 1 μF with well-designed wire connections (PCB layout) to the
upstream supply. In case it is difficult to optimize the input line, use a large tantalum capacitor in combination
with a good-quality, low-ESR, 1-μF ceramic capacitor.

From what it sounds like, the datasheet is suggesting to use a 1 μF ceramic capacitor when the PCB layout can be optimized, otherwise add a large tantalum capacitor (10 μF?). However, I'm confused because searching through these forums, I'm finding some semi-conflicting information.

This post TPS7A7100 Input capacitor says that 1 μF is "fine" whereas this post TPS7A7100 Input Capacitor Concern suggests a 10 μF capacitor instead.

I know it will vary based on application, but is there a general suggested configuration for the input capacitors? Just 1 μF? 1 μF and 10 μF? Something else??

Thanks!
