To be frank, none of these would be my solutions of choices and here are the reasons why:
1-the point and shoot is more than 10 years old and may fail or at least be more restricted in tis possibilities (regarding dynamic range for instance which can be an issue in Portugal–white walls, sea, and sun, I have been to the places you are mentioning)
2-the Canon means bulky (and "visible") equipment that you may have to carry all the time. There are easier solutions but that would entail an investment.
Bottom line, without investing, I would go for the 70D and the 24-105 that will cover 98% or your needs.

Yes, controversial, but I saw these reasons online from Peta Pixel.

1. Handling is not very good on a phone, but a camera is easy to hold, and it has controls that let you make changes easily.
2. The view. The viewfinder of new, mirrorless cameras shows you how changes in settings will affect the final picture. The flip-screen lets you get up or down shots more easily than when using a phone.
3. The flash. Although new cameras seem to be omitting the pop-up flash, it is possible to add a flash unit to the camera. That flash can also be used off-camera to put the light at a different angle. The best you can do with a phone is a small, weak flash.
4. The lens. A modern cell phone might have three separate lenses, but the quality and control aren't as good as what's available for cameras.
5. DOF and bokeh are also lacking in phones, compared with cameras. Selecting a different lens or aperture changes the results you get in the image. That amount of control isn't available with a phone.
6. Movement. The cell phone camera likes to be held steady because it takes multiple shots when you push the button. It's also difficult to follow fast action with a phone, especially considering the multiple shots it takes each time.
7. Selfies. Using the phone for a selfie means using the phone's forward-facing camera, the one with the lowest quality.

The narrator concludes by saying that cell phones are great for quick, casual shots that are going to be shared online, but a real camera will generally give better results.

I've said here many times, that I don't like using a phone as a camera because of the steadiness required while holding the phone away from my body. Holding it steady while taping the button is tricky. I don't always know if the picture has actually been taken. I have to keep my fingers away from the lens. Yes, these are all shortcomings on my part, but they don't apply to a real camera.

I suspect that some of you might disagree with this entire post. That's okay.
