Marc Alhadeff from SonyAlpha.Blog tested both new lenses. About the Sigma 35mm f/2.0 FE he writes:

The Sigma 35mm F2 DG DN Contemporary (616 euros) is an excellent lens that is very well balanced : among the 35mm F1.8/F2 it is one of the sharpest, it has the softest background blur, best bokeh balls , best natural color rendition , best build quality. It has excellent AF and stays compact. So we will forgive its vignetting wide-open and its distorsion that can be easily be corrected if need be.

About the Sigma 65mm f/2.0 FE he writes:

The Sigma 65mm F2 DG DN (700 euros) is an excellent lens and the best of the 4 of the new I series from Sigma for me
Its unusual focal length between 50 and 85mm is very convenient to use for portrait photography
It delivers outstanding sharpness (part of the top 10 sharpest lens for Sony E mount) , super smooth background blur, good bokeh balls, very good skin rendering and color rendition, all that at a reasonable price
The AF is silent, quick, and efficient in photography (a little bit less efficient in video)
Performances are quite similar to the excellent Voigtländer 65mm F2 Macro Apo Lanthar (900 euros), this one is however a manual focus lens but it has some macro capabilities (31cm i.o 55cm min focusing distance) and a bit better color rendering/contrast . So the choice is more dictated by the type of photos you will take
Highly recommended

Dpreview thinks those two Sony cameras are your best choice for travel photography:

Best for family trips: Sony Cyber-shot DSC-RX100 VII

The RX100 VII is a pocketable long zoom camera that does just about everything right, though it doesn’t come cheap. Its 24-200mm equivalent lens offers most of the reach you’ll need for a wide variety of shooting situations, while its maximum aperture of F2.8-4.5 means it’s pretty flexible.
It features probably the best autofocus systems we’ve ever encountered in a compact camera, meaning the little Sony can turn its hand to almost anything you might come across on your travels. There’s also a fairly easy-to-use Wi-Fi system to send images to your phone.
Video is also good – thanks to the camera using the full-width of the sensor – and rolling shutter is minimal. Also, the lack of an ND filter means having to use higher shutter speeds than is ideal in bright conditions, potentially leaving your footage looking less professional than it might. Overall, though, the RX100 VII is the most capable travel camera on the market: nothing matches its combination of size, capability and image quality.

Best for travel photography: Sony a7C

The Sony a7C is a lot larger than the RX100, but it’s the smallest option available if you want image stabilization and full-frame image quality.
It builds on well-known technology and includes an AF system that’s as easy to use as it is powerful. Add in competent 4K video and an impressively long-lasting battery and it becomes a package that can take excellent photos pretty much regardless of what you encounter on your travels.
The 28-60mm F4-5.6 kit lens is conveniently small but isn’t especially bright and has a rather limited range. Adding better lenses makes the package rather less portable. The Nikon Z5 is a little larger but offers comparable image quality at a lower price but, other than the lack of a built-in flash, the Sony a7C would be out choice if you want a travel companion capable of excellent image quality.
