<<"but I guess most trails, easy and challenging, will be pretty full in July?">>
Yes- especially the easy ones.
I suspect that I misread this in your title ( ...Easy Climbing) and in your first post:
<<"but I was wondering if anyone have any recommended hikes with easy
climbing in this area? (I guess that translates to a hike with some
steep parts? but not that steep so you need ropes and stuff. I'm sorry,
my English isn't the best) Or just general advice on full day-trips of
hiking, on mildly-advanced routes.">>
"Ropes and stuff" is "Technical Climbing"
Those are the blue trails on the Swisstopo map.
Red Trails - Difficult trails that require good footwear and hiking staffs are red trails.
Yellow trails don't require special gear...at most,only sturdy footwear. Although, I alwways wear boots to support my ankles. Even the yellow trails can have rough surfaces and significant altitude changes.
For general info and a list of many trails:
For hiking in the Jungfrau region scroll down in this link.:

The hikes that are listed all have a lot of information about the characteristics in the description. This is one of the hikes shown there and might meet your specification of "difficult" and "one day"- but there are many others:
Here is another way to look at trails. I find that it takes me a bit off work to figure out how to get what I want from it. However, you could use it to check out the sections of the Via Alpina in the area, for example. It gives tremendous detail including altitude profiles.

You can also work directly from the map:
map.schweizmobil.ch/?lang=en&land=wanderlan d&route=all&bgLayer=pk &layers=Wanderland&sea son=summer&resolution= 250&E=2631750&N=118900 0
It does not seem to use the color coding of the SwissTopo maps.
map.schweizmobil.ch/?lang=en&land=wanderlan d&route=all&bgLayer=pk &layers=Wanderland&sea son=summer&resolution= 10&E=2637260&N=1160510
Right click on the heavy green lines after you expand the map. If there is information available, it will open up.. Only works on major trails (heavier green lines).
There are others more competent than I to offer other specific suggestions. Perhaps they can add to this thread.
Just keep in mind that, if you are not used to exertion at high altitudes....say,2000 meters and above.... you may find that you need to take it easy for the first few days and pause to catch you breath on the steep ascents.
