Australia

As a daily bike commuter in Melbourne, these concerns exist, but they're really not as bad as you make them seem. Most days in the year it's very enjoyable to ride to work.

I guess this is a problem everyone needs to encounter and in some cases it may well be insurmountable.

I'm lucky I guess in that I don't sweat heaps (although I do sweat). It does get a lot worse when I'm on anti-depressants - that's awful.

Also with the e-bike doing most of the work I'm not over exerted on my way to work.

Proper bike gear wicks the sweat away from your skin. This includes bike shorts with a chamoise (?) This gear is expensive, but it does tend to last a long time.

I have work clothes and some wet wipes in my bag, so I wipe myself down and then get dressed. It's a 10 minute chore.

Another, perhaps more controversial angle is... people can kinda deal with it? There's a difference between not showering for several days and some perspiration resulting from moderate exercise on the way to work. I get that's a personal issue and everyone's ability to encounter that depending on preference and context, but it's unreasonable for colleagues to expect everyone to arrive at work primped and pampered.

As an aside, I'm diabetic. Regular exercise is critically important to my management of this chronic illness and will extend my life expectancy considerably. To me, this is a priority over most other considerations.
