The Crawler looks for content not for design technically you are talking about how to style your H1. That is a CSS topic you don't have to worry about that as long your tag and your content is relevant.

Implement schemas certainly can help you to gain some visibility but there are many factors to keep in mind if you go to the site https://schema.org/ you will notice that there tons of options. So not all the schemas available are supported by Google. In Fact, in your case, you should focus on schemas supported by Google, Facebook, Pinterest etc.

Here you can find more information about the schemas supported by Google and Facebook

• https://developers.google.com/search/docs/guides/mark-up-content
• https://www.facebook.com/business/help/1175004275966513

So if you are working on a travel agency these are some schemas available for your content

• Local Business
• Articles
• Reviews

Also, there are schemas for the business info such as

• logo
• contact info
• location
• social profiles

To help you understand taxonomy systems, first let me explain the
difference between categories, subcategories, and tags. Categories are
used to create large groups within your site. They bundle content that
has a similar high-level topic. Products or blog posts on your site
should fall into a category (a shop category or a blog category).
Because categories are hierarchical they can have subcategories.
Sub-categories fall into at least one category. They bundle a smaller
group of products into a category. Subcategories can have
subcategories too, which bundle an even smaller group, and so on.
By creating categories and subcategories you’ll create a treelike
structure.

Tags on the other hand just group content on certain topics together.
Tags are not hierarchical. You can see them as an index of your site.
They’ll not necessarily fall into a category. They can apply to
products, but to other site content as well.

You can have both a hierarchical and a non-hierarchical taxonomy
system for your website. Ideally, these taxonomy systems are much
alike. For example, you could have a blog on an eCommerce site. In
this case, you’d probably write a lot on topics related to your products.
Maybe about events where you use them, or what to use them for,
how to use them best, comparisons between different products etc.
Therefore, it makes sense that your tags will partly overlap with the
product categories and subcategories of your shop. This is ok. Because
in the end, you’d like to rank with those posts to draw people to the
products you sell. And, if you group products, whether that’s in
categories or tags, it’s easier to make them rank.

Category archives are landing pages
Your category archives are more important than individual pages and
posts. Those archives should be the first result in the search engines.
That means those archives are your most important landing pages.
Thus, they should also provide the best user experience. The more
likely your individual pages are to expire, the more this is true. In a
shop, your products might change, making your categories more
important to optimize. Otherwise, you’d be optimizing pages that
are going to be gone a few weeks/months later.

Categories prevent individual pages from competing
If you sell boxers and you optimize every product page, all those
pages will compete for the term ‘boxers’. You should optimize them
for their specific brand and model, and link them all to the ‘boxers’
category page. That way the category page can rank for ‘boxer’, while
the product page can rank for more specific terms. This way, the
category page prevents the individual pages from competing.

In your case, if you have taxonomies and categories competing for the same keyword is pretty easy, select one them and optimize them.
