I would stay away from a lens with mold. You say that you want this for outdoor use and admit you are not careful. You will most likely be putting this lens in situations that will make the mold grow.
That’s the problem. I also hike, mountain dew, fog, rain , any kind of humidity would make matters worse. Buy a clean lens. Dust is the only flaw I would accept. I don’t think you could have anything serious to lose for not getting that extra 65mm in zoom range.
You get a lens that will work for you and last.

The idea that a mold in a lens can contaminate other lenses is silly. Every lens leaves the factory with mold spores, all that is necessary for it to develop is the right conditions, darkness and humidity.

I realized I have much to learn. I was keeping my moldy DAL50-200mmWR together with my only other lens. I didn't know mold could so easily spread between lenses.

By the way, I always found the pictures from the moldy 50-200 a little soft. Is it possible to tell by the photo only if it's due to mold (or just general lack of skills)?

.
It’s as likely the source of softness is just the lens. That’s a very cheap lens and there can be a lot of variation from one copy to another.

Today, I continue to use my DA18-250mm and I would recommend it without hesitation.
Some people get lucky and get sample from the top end of the sample quality scale.

Does that apply even if the lens is truly disinfected (with ethylene oxide)?

I found the 18-135 for $105, without mold. Seems like a good deal, but I am afraid of regretting missing the wider zoom range.
Sounds like a good deal if in good working order. Its a good lens and if you find that you want more reach then there are plenty of good quality telephoto lenses that are relatively compact and cost effective (e.g. likes of DA 50-200 or maybe an older DA 55-300 would be cost effective. I even have an old sigma 70-300 which has rubbish build but pretty good IQ and is light).

The DA 50-200 is nice and small, weather resistant, good IQ, and it’s cheap. I found mine at Samy’s Camera for $119.00 new. Everywhere else I found it wanted $189.00.

Depending on who you can believe Covid 19 started with one pangolin in a fish market. A little mould isn't going to be a little mould forever. There's an expression 'act in haste, repent at leisure'. BTW I know exactly what it means because I've done it. Too many times.

No mold or fungus on any of my lenses, EVER. This is the "plague" of mistreated lenses, used in humid environments and stored carelessly without having time to dry completely. Plus fungus is alive and will invade the insides of the lens further and destroy coatings. It may contaminate your other lenses too or the mirror box of a DSLR. Let this pass. You can buy something similar in excellent condition for very little money more.

Regards
