There are a lot of plugins that allow users to embed videos using a shortcode. 
Now there’s one more out there.
Video Embeds currently supports YouTube and Vimeo.
Video Embeds allows for control over many of YouTube’s embed paramaters and 
all of Vimeo’s embed parameters. Set default values for all available options 
on the settings page.

And a few other things too.

Video Embeds

Just another plugin that creates shortcodes for embedding videos in posts.

WPXERO

WPXero Iframe adds a dedicated Gutenberg block for external embeds that do not ship a first-party Core block. Use it for videos, maps, audio players, dashboards, booking tools, donation widgets, LMS players, and other iframe-friendly services.
Why this helps SEO and discoverability
<ul>
<li>Editor & directory search — The block title, description, and keyword list match how people look for “iframe block”, “youtube embed”, “maps embed”, “Gutenberg embed”, and similar queries.</li>
<li>On-page context — An optional caption is output as a real <code><figcaption></code> under the embed so your page still has indexable text explaining what visitors are seeing.</li>
<li>Accessible names — Encourages a descriptive <code>title</code> attribute on the iframe for assistive technology and clearer browser behavior.</li>
<li>Crawler-friendly fallback — A <code><noscript></code> block includes a plain link to the sanitized HTTPS embed URL when scripts are off, so bots can still discover the destination.</li>
<li>Performance — Lazy-load mode only loads the small front-end helper script when that option is enabled.</li>
</ul>
Pair it with your SEO plugin (Yoast, Rank Math, SEOPress, AIOSEO, The SEO Framework, etc.) for meta tags, schema, sitemaps, and analytics.
