https://topazlabs.com/gigapixel-ai/Be warned, it definitely has it's limits. However, with some experimentation and exploration of its capabilities, as well as some adequate research into how image editing works, it can also have some fairly stunning successes.
Quality of the original is always incredibly important. Check your dpi (dots per inch) before you do anything. If it's 72 dpi or 96 dpi (standard web resolutions), any editing will have it's limits. Changing to 600 dpi before you do anything can make a dramatic difference in quality. Something as simple as IrfanView can change dpi, save as a new file, then go ahead with your editing & upscaling efforts. You can always go crazy with 800 or 1200 dpi, but there's diminishing returns with that (in some cases it can help). After all your editing is finished, you can always change the dpi back down to something like 300 or 200 dpi for high quality computer screen images.
Also check original quality of the lossless jpeg compression (if that's your source). If your starting with something at high loss/high compression (such as 6 or 7, also known as 60% or 70%) or lower (5 or 50% or under), evaluate how important that image is. It can take enormous effort to upscale images from that quality and still get sad to mediocre results. If your original image is 85% or maybe even 95% or 100%, you stand a much better chance.
Pic in OP is 98% jpeg, so that's nearly lossless and very good to start from. The dpi had not been set. Here's a quickie dirty edit in IrfanView where I set the dpi to 600, cropped off as much of the bottom as I could and still leave hints of the lighted windows, then rescaled it without keeping it proportional. 1920 width would have been too much to stretch it, but 1700 pixels wide is a minor stretch that's not noticeable, and set to 1080 height.
Saved as lossless .png format (always a good idea when possible).
